# Planet Stacker X 1.20 Release Notes

## New Features
- Added the ability to save post-processing settings to a dedicated `.pssettings` document. `.pssettings` can be later loaded to a new image, or even applied during batch processing 
- Added drizzle stacking support with `Off`, `1.5x`, and `3x` output scale options.
- Added the ability to batch process to a `.psImage` image, allowing to adjust any applied `.pssettings`
- Added an explicit invert control in the image editor.

## Bug Fixes

- Fixed an issue where certain sized images would crash when applying frame normalization
- Fixed a bug in analysis logic which could cause certain frames to be weighted more heavily than others
- Fixed a bug where Auto RGB would sometimes fail to register.

## Performance And Reliability

- Made significant performance improvements to the analyze and stacking pipelines by converting several workflows to run on Apple Nueral Engine instead of the GPU.
